To all whom it may concern:

Be it known that I, GEORGE'E. RUDNIGK, a citizenofthe United States, and a resident of Roxbury, Boston, county of Suffolk, and Commonwealth of Massachusetts, have invented an Improvement in Drop-Cover Checks, of which the following description, in connection with the accompanying drawings, 'is a specification, like characters on the drawings representing like parts.

The invention relates to cover supporting and checking means for retaining in open position, and checking or controlling the closing action of a top or cover for talking machines, music boxes and similar cabinets. In the drawings of the embodiment of my invention selected for illustration and description, I

Figure 1 is a vertical sectional view of a conventional form' of talking machine cabinet with my novel cover check in position thereon;

cause it to normally close the ports 7. The cylinder may also have a port 7 if desired although it is not necessary.

In 1ts opposite and upper end the cylinder carries a plunger 13 of any suitable material as metal with a washer 14 as of leather. To the end of the plunger Fig. l, ispivoted or otherwlse loosely connected a cover sup portlng rod 1 1, the upper end of which is movably connected, as by a screw 15, to a hinge or plate member 16, secured as by screws to the cover 17. In this case the member 14 is bent to enable it to clear the edge of the cylinder 1, as it descends. or retaining the plunger 13 and rod 14' 11 1 elevated position I provide a novel catch B1gs. 2, 3, comprising a plate 17 with an elongated aperture 18 therein, which rece ves the plunger 13. When the plunger in raised position Fig. 1, the straight edge of the aperture 18 rests within a slot 19 in the side of the plunger and thereby supports it.

The catch 17 Figs. 2, 3, is provided with a shank 20 which extends through the side of the cabinet 4 and carries .a knob 21 at its end. Between the knob 2l-and the cabinet wall, and countersunk at 22 therein, is a 0011 spring 22 acting normally to retain the plate in plunger engaging or extended position.

The catch is also provided with a neck 23 having a slot 24;through which is inserted a screw or pin-25 which acts not only to preventlateral movement of the catch 17, but the head of the screw acts to keep the catch down adjacent the surface of the shelf 3, while permitting the desired movement thereof.

Obviously when rasing the cover and plunger the beveled edge 13 of the plunger will strike the straight edge of the aperture 18 in the catch plate 17 and force-the latch inwardly against the tension of the spring 22, and the plunger-will continue to move upwardly sliding over the said edge-until the catch plate 17 registers with the slot 19 in the plunger whereupon the spring 22, h a the plate 17 into the said the upward travel will draw or snap notch 19, thus arresting of the plunger. It will also be obvious that after the catch plate 17 has become so seated in the said notch 19 the plunger will be. pre vented from descending by the engagement of the plate 17 with the notch or slot 19..

When it is desired to lower the. cover, one simply pushcsin on the knob 21 disengaging the catch lT'i'rom the slot 1'9 and the cover will descend slowly as the air leaks outbeeneath the disk 12, and escapes by the port 7 ilhthe latter. is provided,

'Ih Fig. li's shown a modification wherein the catchfiiengagesra lug-26 on the side of the rod 14', resting between it and top of the plunger 13.

In Fig,-y5Ifshow a modified form of hinged member. In this construction the cylinder 1 is preferably rigidly mounted in or on a cabinetqshel-f 3* similarly to the way in which it is shown as mounted in Figs; 1 to 4, but at an anglethereto, somewhatas is indicated 1'1-1-F l'g -8,- the lower end of the rod 14:. being rigidly screwed or otherwise. secured to, the

top ofthe plunger 13 in a mannera-lso indicated in Fig. 8. When so constructed the upperend o-f the'ro-d 14: provided with a slidin b1oc-1e which is drilled to receive a rod 2 extending-"between the outstanding arms QS on the member 16, whereby the rod- 1d may slideon therod 27, as may be necessary, and'the plunger may travel freely in the cylinder 1; 1

In Fi'g; (S I "have -illustrated a further modification wherein the rod 14 hassa rigid connection 5 with the plunger 13, and the cylinder'l ispivoted at a fixed point in the cabinet "by'trun'nions 29 'whichare seated indepressions in the plate 30 on the shelfB'and. which permitthe cylinderto swing thereon asis necessary-to accommodate the move-' ment otthe-support'la. Anupperplate 31 serves to retain the trunnions in position. 8*1 showalso a further modification yin-which the cylinder 1 is pivotally mounted at its lower end, as by a screw32 and the plunger also has rigid connection withthe-mernber14.

'As' theplunger descends the cylinder obviouslywr-ll swingion its pivot 82'so far as is necessary to permit the cover to close.

Iii this case, alsol showan additional supportingmember 33' for the cover which may be-"controlled by a catch 17 as in the other instances referred to.

i In all'the 'constructions above described m invention comprises the providing of a talkingmachine or other cabinet, consisting of a main relatively stationary part or portion and a cover-or lid forming a relatively movable partor pprtion; with a drop-cover check deviceconsisting of acyli'nder 1 which is mounted on or secu'redto one of said parts or portions, afrod 1e-'xnounted on or secured to-theothen or" said parts or portions, a plungems to which said-rod 14 isseeured, and a catch 17 operating automatically to hold and retain said plunger at or about one limit of its motion in said cylinder with, the lid or cover of the cabinet in its raised or open position.
